I hope I'm on the appropriate site.
Does anyone know what this thing is?
It has a mini mono plug.
The white square is slippery..but it is not covering double-sided tape.
A white LED did not light up when I plugged it into a mic input on my PC.
I thought there were little holes and it might be a mic but they are small indentations, not holes.
Thanks!

I've seen similar things before used to put remote photodiodes on a remote-operated device. I have one on an HDMI splitter and it uses the same connector. I can't say for sure, but I'm guessing the LED is a photodiode (or an LED being used as a photodiode) and this is meant to be plugged into one very specific device and nothing else. A picture showing the "LED" might be a good idea, by the way.

That's an infrared transmitter for extenders or control systems. That plastic chunk with the IR LED gets glued on a device like TV or Blu-Ray player so that it shines on the device's IR receiver.
